Growing skull fractures.

INTRODUCTION: Growing skull fractures are a rare complication of head injuries (Ersahin et al. in Neurosurg Rev 23:139-144, 2000; Hayashi et al. in Childs Nerv Syst 13:349-351, 1997; Ramamurthi and Kalyanaraman in Neurosurgery 32:427-430, 1970; Zegers et al. in Eur J Pediatr 162:556-557, 2003). Although early diagnosis and prompt treatment are important to prevent the underlying progressive brain damage, the clinical presentation and the morphological investigations are rarely specific or sensitive shortly after the trauma. DISCUSSION: The authors present three cases of growing skull fractures: the use of ultrasonography (US) via the fracture line contributed to early diagnosis and prompt treatment in two cases. US was not performed in the third case, and this delayed management. Treatment consisted of a watertight duraplasty with a free flap of pericranium without cranioplasty. US via the fracture line appears to be a sensitive and reliable method of detecting the dural tears in the early stages of growing skull fractures. CONCLUSION: Duraplasty alone with a flap of pericranium remains the simplest and least expensive method of treatment. Cranioplasty is not necessary in young children.

Depressed skull fractures in children: Treatment using an obstetrical vacuum extractor.

INTRODUCTION: A depressed skull fracture is an inward buckling of the skull bones. It is referred to as a ping-pong ball fracture in neonates; in older children, some fractures take a cup shape mimicking 'ping-pong' ball fractures. OBJECTIVE AND METHODS: The aim of this study was to assess the use of an obstetric vacuum extractor to elevate cup-shaped depressed skull fractures in children irrespective of age. All children admitted into the Central Hospital of Yaounde between 1999 and 2004 with a cup-shaped simple depressed skull fracture and treated with the vacuum extractor were included. RESULTS: Nine children aged from 3 months to 17 years were treated with the vacuum extractor. The cosmetic and radiographic results were satisfactory. The procedure was simple and without any complication. CONCLUSION: The elevation of 'ping-pong-ball-like' or 'cup-shaped' skull fractures in older children (beyond the neonatal period) is a simple, effective and safe procedure.

[Traumatic jejuno-ileal ruptures: apropos of 18 cases at the Central Hospital of Yaounde].

Eighteen blunt small bowel traumas were reviewed in this retrospective study (1986-1996) concerning 12.8% of laparotomies for blunt abdominal trauma. The clinical presentation at admission was peritonitis (9 cases) or hemoperitoneum (4 cases) whereas 5 cases were diagnosed lately because of non specific signs at the beginning. All patients underwent surgery: simple suture or suture after excision of edges (12 cases); resection anastomosis (6 cases). There were no post-operative complications in most of the cases. The mortality rate was 5%. Blunt small bowel traumas are not frequent in our practice. Their diagnostic is often per-operative. If the clinical signs of intraperitoneal lesion are not present, a clinical follow-up by repeated and thorough physical examination can permit an early diagnosis. The surgical treatment is simple, and the prognosis more linked to severe associated lesions than the bowel lesion.

[Blunt trauma of the liver. An analysis of a series of 29 cases].

Twenty nine patients with blunt liver trauma were recorded in the Central Hospital of Yaounde between 1986 and 1996. The average age was 23.4 years, with the 20 to 25 and 5 to 15 age groups being the most affected. The most characteristical clinical presentation was hemoperitoneum with shock. Twenty-three patients were operated (18 in emergency and 5 secondary). While 6 patients benefited from non operative treatment due to their stable hemodynamic state. Exploration of lesions revealed 16 grade I and grade II, 8 grade III and 5 grade IV and V lesions. The operation was a simple suture in 13 cases, selective ligature of hepatic artery in 2 cases and 2 tamponades while in 4 cases the treatment was inactive. The bleeding could not be controlled in 2 cases. Peri-operative mortality was 17.39% and morbidity 21.74%, made up mainly of parietal sepsis. In our practice, blunt liver trauma are generally benign and treatment should be conservative.

[Liver trauma: analysis of 42 cases in Yaounde].

Forty-two cases of liver trauma were reviewed at the Central Hospital of Yaounde between 1984 and 1994. The mean patient age was 22 years, the most commonly involved age group being between 20 and 35 years. Trauma was blunt in 24 cases (57.1%) and penetrating in 18 cases (42.8%). Diagnosis was achieved most frequently by abdominal needle puncture confirming hemoperitoneum. Emergency surgery was performed in 38 cases. In the remaining 4 cases hemodynamic status was stable and surgery was not required. Lesions were classified as grade I and II in 24 cases, grade III in 5 cases, grade IV in 3 cases, and grade V in 1 case. In the remaining 9 cases the grade of the lesion was not mentioned. Management consisted of simple suture in 26 cases, debridement in one case, packing in 4 cases, and a watchful attitude in 4 cases. In 3 cases hemorrhage was uncontrollable. Overall perioperative mortality was 14.2%. The main complication was parietal sepsis which occurred in 6 cases. In the present African series liver trauma was most often benign. This finding suggests that a conservative surgical approach is indicated.

[Posterior urethral valves in children. Apropos of 22 cases].

We reviewed 22 cases of posterior urethral valves over a five year period (January 1986 to December 1990). We looked at initial management before referral to the urologist, treatment and those factors that influence the outcome. We found that nosocomial infection from catheters was the major source of morbidity and mortality. Other determinants of outcome included postobstructive diuresis and the presence of refluxing or obstructing megaureters. The age of the patients was not as important as the degree of obstruction in this group of patients. We recommend percutaneous cystostomy as initial management for these patients as opposed to urethral catheterisation. This should be followed by antegrade or retrograde valve ablation one week later depending on the size of urethra.

[Role of transfontanel cerebral echography in the cerebral exploration in infants from Yaoundé, Cameroun].

During a one year period, central nervous system (CNS) lesions were diagnosed by transfontanella cranial sonography (TCS) in 46 infants at the university medical centre of Yaoundé, Cameroun. The most frequent features were hydrocephaly (22 cases) and perinatal vascular pathology (17 cases). Because of its very low cost/efficacy ratio TCS should be more largely used in the African hospitals for the diagnosis of brain damages in infants.
